April, 2001
2-10 Installation Rosemount Analytical Inc. A Division of Emerson Process Management
Oxymitter 4000
b. Connect Line Voltage
Connect the line, or L1, wire to the L1 ter-
minal and the neutral, or L2 wire, to the N
terminal (Figure 2-9). The Oxymitter 4000
automatically will configure itself for 90-250
VAC line voltage and 50/60 Hz. The power
supply requires no setup.
c. Connect 4-20 mA Signal and Logic
I/O/Calibration Handshake Leads
(Figure 2-9)
1. 4-20 mA Signal. The 4-20 mA signal
represents the O
2
value and can also
operate the Model 751 Remote Pow-
ered Loop LCD Display or any other
loop powered display. Superimposed
on the 4-20 mA signal is HART infor-
mation that is accessible through a
Model 275 Handheld Communicator or
AMS software.
2. Logic I/O/Calibration Handshake. The
output can either be an alarm or pro-
vide the handshaking to interface with
an IMPS 4000. For more information,
refer to paragraph 7-3 and the IMPS
4000 Intelligent Multiprobe Test Gas
Sequencer Instruction Bulletin.
3. If autocalibration is not utilized, a
common bi-directional logic contact is
provided for any of the diagnostic
alarms listed in Table 7-1. The assign-
ment of alarms which can actuate this
contact can be modified to one of
seven additional groupings listed in
Table 3-1.
The logic contact is self-powered, +5
VDC, 340 ohm series resistance. An
interposing relay will be required if this
contact is to be utilized to annunciate a
higher voltage device, such as a light
or horn, and may also be required for
certain DCS input cards. A Potter &
Brumfield R10S-E1Y1-J1.0K 3.2 mA
DC or an equal interposing relay will be
mounted where the contact wires ter-
minate in the control/relay room.
d. Install terminal block cover (27, Figure 6-1)
and secure with cover lock (34), gasket
(33), and screw (32).
